Checkbox steals input when set to "Self Hit Test Invisible"

There is an issue with the checkbox taking input when the visibility is set to "Self Hit Test Invisible". It should not be taking input as it should have the same properties as "Hit Test Invisible", which works as intended with the CheckBox. This issue does not affect other components. This issue is not a regression
